Vesper Launches Adaptive ZeroPower Listening for Smart Home Devices
Vesper, a supplier of piezoelectric sensors, has introduced VM3011, an intelligent digital microphone with Adaptive ZeroPower Listening, a power-saving architecture that extends battery standby life by 10 times for always-listening smart home systems.
Adaptive ZeroPower Listening automatically learns the acoustic characteristics of the environment in real time, allowing the system to ignore background noise and only wake in response to keywords or other desired acoustic triggers. This allows the system to hibernate more than 90 percent of the time.
"Existing always-listening systems run continuously and must be plugged into an electrical outlet. The VM3011 creates a new paradigm where these sytems can now run for months or years on battery power," said Matt Crowley, CEO of Vesper, in a statement. "This technology will power a new class of products, such as always-listening far field TV remotes, always-listening smartwatches, home security cameras and doorbells with extended battery life, and many other systems. Vesper has already engaged with lead customers who plan to roll out products with the VM3011 later this year."
